This is a common misconception. It stems from the erroneous conclusion that since large scale conspiracies (e.g., Watergate) have previously been uncovered, therefore all large scale conspiracies will inevitably be uncovered.

The holocaust of the Jews, for example, was a vast state-sponsored conspiracy that likely would have been kept from the German people, and the world, had not Germany lost the war, and their secret exposed. Had they won the war, it would likely have been rumored to have happened, but those who advanced the possibility of that rumor being true would have been dismissed as cranks.

Remember, the bigger the lie, the harder it is to credibly refute.
